Details - Four-row tapered roller bearings

Four-row tapered roller bearings used for rolling-mill roll are easy to service and check, and are designed to have the highest load rating possible for the limited space round roll necks. Also, they are designed for high speed to satisfy the demand for fast rolling.

The four-row tapered roller bearing with cylindrical bore is designed to maximize the load capacity with minimum space, and is widely used for roll neck of lower medium speed rolling mills.

The bearing of this type is made up of one double outer ring, two single-row outer rings, two double inner rings and inner ring spacer/outer ring spacer.

Since each component is not interchangeable, it is necessary to assemble each component as specified with care taken to the matching marks marked on the bearing.

Since the internal clearance has been preadjusted, the bearing can be used with ease without any necessity of readjustment.

Since tee bearing needs to be removed frequently and is clearance-fitted to the roll neck, the inner ring spacer is hardened to avoid wear.

The lubrication grooves are provided on both sides of the inner ring spacer to allow the lubricant to be readily passed to the roll neck. The lubrication groove and lubrication holes are provided at the outside diameter of double outer ring and outer ring spacer.

Four-row tapered roller bearings provided with lubrication holes and O-rings on the outer ring is used for oil mist lubrication.

Sealed type four-row tapered roller bearings have oil seals on their side faces and in between inner rings, and O-rings on their outside surfaces to achieve the purposes below.

  • Reduction in frequency of disassembly, washing, and reassembly.
  • Improvement in working environment of disassembly, washing, and reassembly.
  • Reduction in grease consumption.
  • Improvement in ambient surrounding rolling mills.
